Seats for Softails...

I have a custom built Softail that currently has a solo seat. I use a suction cup pillion pad when I have a passenger. As you can guess I get some "complaints" about this set up from the ladies. :rofl

I was wondering if there is any type of seat out there that would attach with out having to drill a hole in my rear fender for the rear seat bolt. I really would rather not drill this hole if I don't have to.
